Taurine
Taurine is a type of amino acid that is essential to our body. Our body makes taurine on its own. In our body, taurine is found in the brain, retina, blood cells, heart, etc.
Taurine also enhances our performance. Rockstar contains 0.04% of taurine. Which will not only help in enhancing our performance but also help in electrolyte regulation.
Guarana Extract
Guarana is a plant that is native to Brazil, making the Amazonian tribes use the plant for therapeutic or medical processes.
Guarana Extract is rich in antioxidants which is why it is used in energy drinks quite often. It helps in improving your focus and reducing ugly fatigues. Multiple studies show, that Guarana can help in weight loss too!
Ginseng Root Extract
Ginseng Root Extract is extracted from Ginseng. Ginseng is also a plant and can be used as a herbal remedy for many health issues.
The herb is found largely in China, Korea, and America. Ginseng Root Extract is rich in antioxidants too which leaves multiple health benefits, such as:
- Helps in reducing inflammation

Caffeine Content of Rockstar
Each serving of 16 fl. oz Rockstar contains 160 mg of caffeine.
160 mg might not be the highest-caffeinated energy drink in the market, but it’s still strong enough and gets the job done. Unless your caffeine tolerance is really high, Rockstar should do the job right.

If your caffeine tolerance is low, then Rockstar might not be the right energy drink for you. Caffeine content depends on your body’s ability to consume it.
It’s also wise to keep your daily caffeine intake in mind, which is 400 mg for both healthy males and females, recommended by the FDA. Consuming any more caffeine may often lead to problems like these:
- Insomnia
- Anxiety
- Shakiness
- Headaches
- High Blood Pressure, etc.
So, even if you are a regular caffeine consumer, drink it in moderation.
How Much Sugar Does Rockstar Have?
A single 16 fl. oz can of Rockstar contains 24g sugar.

Given the sugar content, Rockstar energy is not as sweet. However, it still has a lot of added sugar.
The AHA (American Heart Association) recommends 24g sugar per day for females and 36g sugar per day for males. That is 6 teaspoons of sugar per day for women and 9 teaspoons for men.
While some added sugar is alright, as it helps in boosting your energy, too much added sugar will cause health problems like:
- Inflammation
- Diabetes
- Weight Gain
- Obesity, etc.
If you consume too much sugar, you will most likely be welcomed with “sugar-crash“, also known as Hypoglycemia.
How Many Calories in a Can of Rockstar?
An original can of Rockstar has 122 calories per serving.
Calorie count doesn’t matter that much in an energy drink if it’s heavily caffeinated and has sugar. Rockstar is not loaded with caffeine but it has a significant amount of sugar.
Fortunately, the calorie count in a can of Rockstar is not sky-high. So you can drink a can of Rockstar whenever you want a boost of energy or just want to stay awake during those night-shifts.
But it’s always a good idea to know your average calorie content. The recommended daily calorie intake is 2,500 calories per day for men and 2,000 calories for women. However, keep in mind that these values will vary depending on your weight, physical activities, and a couple of other things.
If you’re calorie or health-conscious, you can always check the calorie content and nutritional label if you just flip your Rockstar can.
If you’re on a diet and want to drink Rockstar, you can but in moderation.
Vitamins and Macro-Nutrients In Rockstar
Rockstar contains only 3 vitamins. They are vitamin B3 (Niacin), B6, and Vitamin B12. This may not look like much, but these 3 vitamins play vital roles in your body. Check the table for more.
Vitamins | Benefits | Amount Present in 16 fl. oz Can | Tolerable Intake |
Vitamin B3 (Niacin) | Lowers LDL cholesterol, can help in preventing heart diseases and improves skin. | 16mg | 35mg |

The macro-nutrients in a can of Rockstar include protein and carbohydrates where 26g of carbohydrate is present along with 2g protein, per can.
How long does Rockstar Energy Drink last?
The effects of Raze Energy could last several hours to a full day. This depends on your metabolism, caffeine, and any other ingredients like sugar. However, the initial burst of energy from an energy drink typically lasts for a few hours.
While energy drinks may provide a quick energy boost, it’s important to be aware of their potential negative health effects, including increased blood pressure, heart palpitations, and difficulty sleeping. Some people may also experience anxiety, headaches, and nausea after consuming energy drinks.
Does Rockstar keep you awake?
Rockstar Energy does keep you awake. Rockstar energy drinks contain caffeine, which is a central nervous system stimulant. Caffeine can help you feel more alert and awake by blocking the effects of adenosine, a chemical in the brain that can make you feel drowsy.
While caffeine can help you stay awake and alert, it’s important to use energy drinks like Rockstar in moderation. Consuming too much caffeine can lead to negative side effects, such as headaches, jitters, and trouble sleeping amongst other more severe side effects.
Does Rockstar Energy Actually Work?
Rockstar Energy surely works. With each can containing 160 mg caffeine and 24g sugar along with a generous amount of multi-vitamins, Rockstar works.
The caffeine in the energy drink will help in keeping you awake and staying focused. The whopping 24g sugar will help in giving you the perfect boost of energy.

Is Rockstar Energy Bad For You?
If consumed within limits, Rockstar Energy is not bad for you.
In fact, there are certain ingredients in Rockstar that are rather beneficial for our health than harmful. For example, Taurine, Guarana Extract, Ginseng Root Extract, etc.
Can You Drink Rockstar Energy Every Day?
With the high sugar content and 160 mg caffeine, you may drink Rockstar Energy every day, but it is in no way healthy.
Now, an energy drink’s job is to provide you a boost of energy and keep you awake. Rockstar energy drinks will do exactly that. Not just Rockstar. Any good energy drink will not fail to do that.
But, if you consume Rockstar every day, it will be unhealthy for your physical health. You will find it very hard to focus on anything without an energy drink. Borderline is, it affects your mental health, too.
Benefits Of Rockstar
While Rockstar may contain quite a bunch of added sugar, overall, the energy drink still is beneficial for your health.
If the energy drink is consumed in moderation, some of the benefits will include:
- Increase in focus and concentration.
- Increase in energy levels
- Will make you feel refreshed
- Helps you stay awake
Side-Effects Of Rockstar
Rockstar has a lot of benefits but the side effects are also significant if you are reckless with your consumption and decide to go overboard.
Now, if you don’t moderate your consumption, you may face problems like:
- Headaches
- Nausea
- Rapid Heart Rate
- Restlessness
- Lack of focus
Energy drinks will do their job in providing you energy. It is your job to control your consumption.
How Many Rockstar Cans Can You Drink Every Day?
You stick to drinking one can of Rockstar Energy per day.
The explanation is, Rockstar contains a lot of sugar. A 24g sugar takes up a lot of sugar from your daily sugar intake, not just that, too much sugar intake can cause a lot of problems. Starting from mood swings to weight gain.
However, Rockstar is more on the safe side, caffeine-wise. With 160 mg caffeine per serving, it will not affect your health unless you are reckless with your consumption.
Apart from that, sticking to one can of Rockstar is the best option, considering its sugar content.

Alternatives to Rockstar
Rockstar is a great energy drink to consume if you just want a boost of energy and a quick increase in your focus. But if the energy drink is not in your forte, here are other drinks you may try instead:
The Bottom Line
Rockstar is a good energy drink of choice. However, I feel like there are some parts where Rockstar can improve.
For reference, they can lower their sugar content in their regular energy drinks and introduce fewer calories too. That way, it’s way healthier and better.
Other than that, with 160mg caffeine and 24g sugar, it sure will keep you awake and alert the whole day. And if you have moderate caffeine tolerance, the energy drink will work.
